Fomblin® ZLHT Grease

 

Product Overview

Fomblin® ZLHT (now known as Klüberalfa GR ZLHT) is a homogenous white grease having excellent lubricating properties. It can be used in continuous operating conditions, at temperature intervals ranging from -80˚C to 200˚C ( the widest operating temperature of the range of greases ).

Fomblin® ZLHT’s chemical and physical properties make it suitable for use in the aerospace industry or in chemical plants where lubricating parts are subjected to very wide thermal cycles.

Applications

A few of the critical uses of Fomblin® greases include:

Bearings operating at extremely low or high temperatures or subject to high thermal range.

Mechanical parts in contact with aggressive chemicals or oxygen.

Nuclear industry lubricants

Instrument lubricants

Lifetime sealed, maintenance-free bearings

Bearings exposed to high temperatures, moisture and aggressive chemicals
